Abstract
A series of near-UV to blue emitting Sr3Lu2(Si3O9)2:Ce3+ phosphors were prepared by a solid state reaction. The optical properties of synthesized phosphors were investigated as a function of Ce3+ concentration and temperature. These luminescent materials strongly absorb UV radiation shorter than 360Â nm. The optimal Ce3+ concentration was 0.1% (external quantum efficiency ca. 45%). Temperature dependent measurements showed that Sr3Lu2(Si3O9)2:Ce3+ phosphors possess good thermal stability and loses only about 40% to 50% of initial intensity in the temperature range of 77-500Â K depending on activator concentration.
